Abstract
A method of packaging a radioactive waste including the steps of: (a) providing a containment enclosure having (i) an outer polymeric fabric layer and (ii) an inner polymeric fabric layer, wherein the outer and inner polymeric fabric layers are thermally stable to −40° F.; (b) placing a radioactive waste within the inner polymeric fabric layer; and (c) closing an outer closeable flap on the outer polymeric fabric layer.
Claims25
A radioactive waste containment enclosure comprising:
- (a) a dual layer outer polymeric fabric combination including (1) a first polymeric layer, and (2) a 6 to 45 oz non-woven second polymeric layer, wherein the first polymeric layer and the non-woven second polymeric layer are joined together;
- (b) an inner polymeric fabric combination positioned within the outer polymeric fabric combination, the inner polymeric fabric combination including (1) a 4 to 30 mil substantially impermeable third polymeric seal (IPS) layer, and (2) a 6 to 45 oz non-woven fourth polymeric layer;
- and
- (c) wherein the first, second, third and fourth polymeric layers are thermally stable to −40° F.

A containment enclosure formed of at least three polymeric layers, the at least three layers comprising:
- (i) an outer 6 to 45 oz woven or non-woven polymeric layer;
- (ii) an inner 6 to 45 oz woven or non-woven polymeric layer;
- (iii) a 4 to 30 mil substantially impermeable polymeric seal (IPS) layer between the outer and inner polymeric layers;
- (iv) wherein all of the at least three polymeric layers are thermally stable to −40° F.
